3 Claims.

This invention relates to extension tables such as dining room andbreakfast tables and it has for its primary object to enable the tabletop to be opened and closed in a uniform straight line 5 movement with aminimum of power and without skewing or jamming.

Another object of the invention is to provide an equalizer of simple andnovel construction for an extension table to facilitate opening andclosing the table top easily and with little effort.

And a further object of the invention is to provide an equalizer for thetop of an extension table comprising few parts of simple constructionadapted for attachment to the table top so that the power will beapplied on one end of the table top and the resistance will be exertedon the other end of the table top in a straight line movement, inopening and closing the table top, whereby the operation of opening andclosing the table top is facilitated and accomplished with a minimum ofeffort and the two parts of the table top are caused to move withoutskewing or jamming and into full contact with each other or with afiller or extension leaf inserted therebetween.

I have selected one type of breakfast table to illustrate my inventionin the accompanying drawing and referring thereto Fig. 1 is a bottomplan View of the table in closed position and showing it without thefiller leaf in full lines and with the filler leaf in broken lines;

Fig. 2 is a longitudinal sectional view on the line 22 of Fig. 1; and

Fig. 3 is a transverse sectional view on the line 33 of Fig. 1.

Referring to the drawing, the table frame comprises side rails 4, endrails 5, legs 6, corner brackets '7 and cross bars 8 secured together inany suitable way customary in table manufacture. The table top comprisestwo equal parts 9, 9 and a removable extension or filler leaf 10 whichis stored in any suitable position under the table top, or elsewhere,and is adapted to be inserted between the two parts 9, 9' for enlargingthe table. The table is provided with suitable guide and stop devices asis customary in extension tables. These devices may be made in the formof guide bars 11 fastened to the underside of the table top and providedwith grooves to receive guide pins 12 on the side rails, and the siderails may be provided on their upper edges with grooves 13 to receiveguide and stop pins 14 on the underside of the table top. The grooveshave end walls 15 which are engaged by the pins 14 to limit the in andout movements of the table top parts.

1934, Serial No. 750,782

An extension lever 16 is pivoted at one end 1'7 to the top part 9' andis pivotally connected at its other end 18 to one end of a link 19 whichis pivoted at its other end 20 to the top part 9. The lever 16 has afulcrum bar 21 pivoted at 22 to the lever midway between its ends andalso pivoted at 23 to one of the cross bars 8. This bar 21 provides afloating fulcrum for the lever 16 at 22 and facilitates the operation ofthe equalizer. The lever is pivoted at 1'7 and the link is pivoted at 20preferably in the center line of the table so that in opening and inclosing the table top the force will be applied at 20 and at 1'7 in astraight line and preferably in the center line of the table to moveboth parts 9 and 9 of the top uniformly, evenly and in a straight line.

The equalizer comprises only a few parts. It is simple in construction,it operates easily and with little effort and it causes the two parts ofthe table top to move toward and from each other uniformly and in astraight line, thereby avoiding skewing and jamming of the parts.

I have shown the invention embodied in a simple form in one kind ofextension table and I reserve the right to embody it in other tables andto make such changes, alterations and modifications as may be necessaryfor this purpose, or for other purposes, within the scope of thefollowing claims I claim:

1. An extension table comprising a frame, a table top having two partsslidably movable toward and from each other on the frame, an equalizerfor causing one part of the table top to move relatively to the otherpart when force is applied to move the other part, said equalizercomprising a lever pivoted at one end to one part of the top, a linkpivoted to the other end of the lever and to the other part of the top,and a floating fulcrum for said lever.

2. An extension table comprising a frame, a table top having two partsslidably movable toward and from each other on the frame, an equalizerfor causing one part of the table top to move relatively to the otherpart when force is applied to move the other part, said equalizercomprising a lever, a link pivoted at one end to one end of the lever,the other end of the lever being pivoted to one part of the top and theother end of the link being pivoted to the other part of the top, bothof said last mentioned pivots being in alinement with each otherlengthwise of the table, and a floating fulcrum for the lever.

3. An extension table comprising a frame, a table top having two partsslidably movable toward and from each other on the frame, an equalizerfor causing one part of the table top to move relatively to the otherpart when force is applied to move the other part, said equalizercomprising a, lever pivoted at one end to one part of the top,
